我记得相关 代词 指代 问题 上有提过 代词优先就近指代,但是不能指代介词后跟的名词 是么?
下面这道题中
Many population studies have linked a high-salt diet to high rates of hypertension and shown that in societies where they consume little salt, their blood pressure typically does not rise with age.
(C) shown that in societies where little salt is consumed,
(D) they showed that in societies where little salt is consumed,
C是对的,D是错的。先不管D的they是多余的问题。Prep上面的解释说,因为they在这里指代不清楚,有可能是studies也有可能是rates。
我有点儿不解的是 rates应该是跟在介词to之后的,还能指代么?
以及
Whereas the use of synthetic fertilizers has greatly expanded agricultural productivity in many parts of the world, an increase in their use can create serious environmental problems such as water pollution, and their substitution for more traditional fertilizers may accelerate soil structure deterioration and soil erosion.
这句话中their为啥就能直接指代fertilizers呢?
谢谢!! |
